Description

The HVD-2500 twin rotor vacuum pump incorporates a number of engineering innovations, provides the highest pumping speed and best ultimate pressure with maximum safety in combination with dry and oil vacuum pumps.
Advantages
1. Increased process gas throughput due to the possibility of significantly increased speeds
2. Reduced pumping time by starting operation at atmospheric pressure
3. Highest operational reliability when the pumped gas parameters meet the requirements of the pump
4. Pump protection in case of cooling water failure by processing the temperature sensor signal
5. Simple electrical integration via digital and analogue interfaces
